All examples quoted here are from the OED; I first learned of this eggcorn from Ullmann (1962).

In the original samblind, the sam- is cognate with semi-; the original meaning is ‘purblind’, as Elyot indicates. The reanalysis of sam- as sand has not only altered the form of the word, but has influenced its interpretation as well, as exemplified by Shakespeare’s sand/gravel pun and by Johnson’s “small particles” definition.

The original samblind is long gone, and even the new form is labelled “arch., poet., and dial.” by the OED.
